ADV Photo Association Game

One person posts a photo then another person posts any other photo according to the association that the first photo prompted him/her. And so on and so on... your post should be in response to the post directly above yours.

Requirement: Every photo must have a motorcycle!

example:
This photo:
might be replied to with this photo:
which might be responded to with this photo:
which could be associated with this photo:
...and so on and so forth.

PHOTOS ONLY PLEASE! Minimal discussion accept to maybe clarify the association if not obvious
